Ice Dams 101
Glistening icicles hanging from your home's roof may catch your eye, but they could be signaling the presence of ice dams – a potential threat to your home's integrity. When left unattended, these ice formations can lead to significant damage. The good news is that there are proactive measures you can take to prevent the formation of these winter hazards. Even though in Hunterdon County we don't have winters as severe as we did in the past, ice damns are still a cause for concern on our homes.
Understanding Ice Dam Formation:
Ice dams typically develop after heavy snowfall followed by freezing temperatures. The process unfolds as warm air from your home reaches the attic, warming the underside of the roof. This warmth causes the snow and ice on the roof to melt. However, when the melted water encounters the colder overhang, it refreezes, creating a dam. This ice buildup obstructs the natural runoff, leading to potential water seepage into your attic and, in severe cases, through ceilings and walls.
Potential Damages:
Although ice dams may appear harmless, their consequences can be severe. Untreated ice dams can:
Compromise attic insulation
Loosen shingles
Detach gutters
Stain ceilings and walls
Peel paint
Damage sheetrock
Warp floors
Contribute to mold and mildew growth
Preventive Measures:
Thankfully, homeowners can take several steps to prevent ice dams:
Clear gutters before the first snowfall to prevent ice buildup that could damage gutters.
Ensure proper functioning of downspouts.
Insulate your attic effectively to maintain consistent temperatures and prevent warm air from reaching the roof.
Verify proper ventilation in the attic to discourage ice dam formation.
While these tasks can be beneficial, some may involve potential risks. When uncertain, it's advisable to seek professional assistance.
Safety Tips:
In the event that an ice dam forms, follow these safety guidelines:
Avoid going on the roof due to slippery conditions.
Refrain from chipping at the ice from below to prevent injury or shingle damage.
Use a long-handled broom or roof rake to safely remove snow from the roof.
For ice removal, fill old nylon stockings with calcium chloride ice melt, placing them on the ice to create a path for water runoff.
Your safety is important, and in situations where expertise is needed, consulting a professional is the best course of action.
